Sonic the Hedgehog in Robotnik's Labratory
This is the first book in the series. A slightly altered stock art is holding a test-tube while some green face flies around in the 'chemistry set' background. Is he summoning the Green Goblin?
"Yo dudes, where'd everybody go! Why can't Sonic and Tails find their
friends? It's not long before the spiky sprinter realises that they're being held in the laboratory of Dr Ivo Robotnik: the maddest, baddest man in the whole of Mobius. Can Sonic rescue his friends in time? Or will the traps and mazes of Robotnik's laboratory prove too much for even this way-cool hedgehog to deal with?"
